' SHOCK-ABSORBER.

Application file d July 18,

To all whom it may concern:

Be it known that I, Loom H. OBERREICH,

a citizen of the United States, residing at Indianapolis, in the county of Marlon and.

structure thereof, which cushions direct shocks and limits the movement of, the

shock-absorber lever upon rebound, and

which may also resiliently oppose upward movement of the main sprlng after the rebound movement of the lever has been stopped.

The accompanying drawing illustrates my invention: Figure 1 is a fragmentary elevation of a frontaxle and spring of an automobile, equipped with one form of shock absorber embodying my invention, 1n which form there is a positive limit of. the rebound; Fig. 2 is a plan, on a smaller scale, of theshock-absorber lever of Fig. 1; Fig. 3 is a plan, on a small scale, of the saddle which is mounted on the axle; and Fig. 1

' shackle or link from the eye of the perch,

is a fragmentary elevation somewhat similar to Fig. 1, but showing a slightly different form of shock absorberembodying my invention, in which form therebound 1s resiliently opposed.

The ma-inspring 10 and the front axlell are of standard Ford construction, and the end of the spring 10 is supported from the standard perch 12, with which the axle is' provided. .As shown, this perch is reversed from the. position shown in the Ford car, by having the right and left hand perches 1nterchanged, so that the perch projects from the axle both upward and outward; this,

however, is not essential. The end of'the spring 10 and the end of the perch 12 are both provided with eyes. None of this is at all changed from standard, savefor the interchange of perches as noted. In the standard construction, however, the eyes of the perch and of the main spring are connected by a, shackle or link. I remove that and may or may not remove it from the eye of the main spring, according as I use the form shown in Fig. 1 or theform shown in Fig. 4. In place of pivoting this link to the eye of the perch, I pivot on said perch eye,

20 on the perch 12 or on some other suitable support fixed on the axle, a shock-absorber lever 13. This lever extends outward to form a downwardly curved stop'finger 14, which may engage the upper surface of; theaxle 11 to positivelylimit the lever movement which occurs upon rebound. The lever 13 also proects inward past the end of the main spring 1t), thls inwardly projecting portion being bifurcated to provide a pair of springseats 15 for receiving the upper ends of a pair of compression springs. 16 whichoppose the downward movement. of the inner end of the lever 13. The lower ends of the springs 16 are received in spring-seats 17 which oppose the spring-seats 15 and which are provided in any suitable manner, as by belng parts of a saddle 18 whichis clamped to the axle 11 in any suitable manner, as by clamping bolts 19. Between its pivot point and the spring-seats 15, a pivot pin21 to which 1s attached a link 22, which is also connected to the pivot pin 23 in the eye of the main spring 10. This. link 22 may be the link which in the eyes of the mainspring and of the perch; this construction is shown in Fig. 1. On the other hand, itmay be, a different; link, formed with an upwardly projecting and outwardly curved arm 24: in addition to the link portion, as is shown in Fig. 4; in this case, the free end of the arm 2 1 is provided with a downwardly facing spring-seat 25 which the lever 13 carries receives the upper end original car connected the 7' of a compression spring26, the lower end of I which is received in a spring-seat 27 opposing the spring-seat 25 and forming part of the lever 13 on which it is located just above the stop arm 14. i

In operation: When the main spring 10 is pushed down toward the axle 11,'it spreads its ends to turn the link 22, and also forces downward the inner end of the shock-absorber lever 13, to compress the springs 16.

lever13 may continue until the stop finger 14 engages the axle, which engagement may stop the movement of the lever'13 and also tends somewhat to stop the rebound. It

' h Opposition which the springs 16 offe t x spring 10 iv does not positively stop the rebound, how- 7 ever, but allows the rebound to continue to movement a spring and axle. are pushed and axle of an automobile,

' lever being free some extent by the turning of the link 22 on its pivot pins 21 and 23 and the resultant coming together of the ends of the main spring. This I 22 is unopposed in the arrangementshown in Fig. 1, save by the resistance which the spring 10 may offer by the forcing together of'its ends; but in in Fig. I, this turning movement of the link 22 is resiliently opposed by the action of the rebound'spring 26 on the arm 2 k.

I claim as my invention: 7

1. In combination with the main spr ng and axle of an automobile, a lever having a fixed pivotal support upon sa d axle beyond the end of themain spring, connecting said lever to. the main spring, a spring acting between said leverand said axle and resiliently opposing, the lever which occurs when the ma n together, said lever being, free from spring opposition to its movement in the opposite direction, and

2. In combination a stop for limiting a lever havlng a fixed pivotal support upon said axle beyond the end of the main spring, a link connecting, said lever to the mam spring, a spring acting between axle and resiliently opposing, the lever movement which occurs when the main spring and axle are pushed together, said from spring opposition to its movement in-the-opposite direction, and
